International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The system throughput capacities of modern data systems exceed the bit rate capacity of current range telemetry capabilities. Coupling this with the shrinking spectrum allocated for telemetry results in a serious problem for the Test, Training, and Space telemetry users. Acknowledging this problem, the Department of Defense (DoD) has embarked on an aggressive improvement and modernization program that will benefit both the government and commercial range providers and users. The ADVANCED RANGE TELEMETRY (ARTM) program was created and funded by the Central Test and Evaluation Investment Program (CTEIP) under the Office of the Secretary of Defense, Undersecretary for Acquisition and Technology to address this problem. The ARTM program goals are to improve the efficiency of spectrum usage by changing historical methods of acquiring telemetry data and transmitting it from systems under test to range customers. The program is initiating advances in coding, compression, data channel assignment, and modulation. Due to the strong interactions of these four dimensions, the effort is integrated into a single focused program. This paper describes the ARTM program and how academia research, emerging technology, and commercial applications will lay the foundation for future development.

abstract: Traditional wireless communication systems operate in duplexed modes i.e. using time division duplexing or frequency division duplexing. These methods can respectively emulate full duplex mode operation or realize full duplex mode operation with decreased spectral efficiency. This thesis presents a novel method of achieving full duplex operation by actively cancelling out the transmitted signal in pseudo-real time. With appropriate hardware, the algorithms and techniques used in this work can be implemented in real time without any knowledge of the channel or any training sequence. Convergence times of down to 1 ms can be achieved which is adequate for the coherence bandwidths associated with an indoor environment. By utilizing adaptive cancellation, additional overhead for re-calibrating the system in other open-loop methods is not needed. / Dissertation/Thesis / Masters Thesis Electrical Engineering 2016
